Microcementi™ CSA Binder, is produced using a mixture of limestone, clay and gypsum and is known as a green cement, producing 25% less CO2 emissions than Ordinary Portland Cement during the fusing process. Due to its low shrinkage properties with high early strength, Microcementi™ CSA Binder is ideal for non-shrink grouts, precast, lightweight concrete and glass fiber reinforced concrete.
